Not a Thing to be Waited for

As a child, Stiles had cracked how the whole soulmate business worked. The names on his wrists had a specific order to place them as either his enemy or ally. His own Mr. Right was called Scott and, after meeting him, Stiles knew his theory was sound; his mom and dad had each other's names on their right wrists too, so there was no way that could be wrong. On his left he carried the name Peter. He had never met him but, when he did, he would know to be wary of him. After all, he was clearly his destined adversary...Right?
